 Jim Busser sent this Guide feedback to macports-mgr:

 {{{
 Under 4.2 Creating a Portfile > 14. Port dependencies

 where it says
         A port's dependencies are ports that must be installed before
 another port is installed.
 and gives the example
         depends_lib
 might it be worth cautioning to
         see 5.3.2.1 (bullet 2) on preferred use of the -append, -delete
 keyword modifiers
 }}}

 This should be considered not only for the `depends_lib` example but also
 for the `configure.args` example and the `categories` example, since
 portgroups commonly define those.

Comment(by ryandesign@…):

 Actually I was trying to copy Jim's email into the ticket verbatim, and
 provide visual distinction between the text he sent me and my commentary
 on it.
